SWITCH-POINT DRAIN-BOX.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed June 15, 1914. Serial No, 845,151.

T all whom it may concern:

Be it known that I, GEORGE ARTHUR ER- RINGTON, of the city of Toronto in the county of York, in the Province of Ontario, Canada, have invented certain new and use ful Improvements in Switch-Point Drain- Boxes, of which the following is the specification.

w My invention relates to improvements in switch point casings and drain boxes therefor and the object of the invention is to devise means whereby all moisture and foreign --matter may be drained off from the switch point casing and conduits containing the switch point mechanism and whereby water so collected is carried off to the sewer and the foreign matter retained in the drain box so as to be easily removable therefrom and it consists essentially of a (shaped rail section forming the switch point casing having an open center and cross bars extending across such open center and a switch point swingably supported thereon, a boxing extending below the switch point casing and having an inclined bottom provided with an opening in the side wall of the casing in the lowest point in the casing, an inlet orifice extending into the casing and leading from the conduit containing the switch operating mechanism and a concave sieve removably supported within the boxing and extending from end to end of the same intermediately of its height as hereinafter more particularly explained by the following specification.

Figure 1, is a general plan view showing the location of my drain box in relation to the conduits containing the switch operating mechanism and with the cover thereof removed. Fig.- 2, is an enlarged plan view of the drain box as shown in Fig. 1. Fig. 3,

' is a cross sectional view on line m@ Fig. 2.

Fig. 4, is a longitudinal section through Fig. 2, on line mg Fig. 3.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is one of the track rails.

A is a substantially Y-shaped rail section, such section comprising the arms A and A and having an intervening open portion A This open portion A extends from the diagonal line A on one side to the edge of the rail A on the other and from the inner edge of the drain box A on the right of Fig. 2 to the line A on the left. Across this open portion A extends the cross bar A The arms A and A are provided with side openings A and A divided by vertical bar members A A is a switch point pivotally supported on one of the cross bars A by a suitable bolt A.

B are conduits containing the operating mechanism for operating the switch point. I do not describe this as it forms the subject matter of a co-pending application filed of even date herewith.

6 is a slot formed in the switch point in proximity to its free end and through which the switch point lever 7 extends.

8 and 9 are pins'extending through the lever 7 at each side of the switch point there by connecting the switch point and lever together.

C is the drain box proper provided with an inclined bottom C. (see Fig. 8), outlet opening C and inlet opening C C is a supplemental duct (see dotted lines Fig. 1) connecting the conduits B with the inlet orifice C I preferably form my drain box with a dividing partition D having a concave upper face.

D and D are sieve frames provided with suitable sieves, the frames also being formed concaved in cross section. The sides of the sieves rest upon lugs E and E extending inwardly from the sides of the drain box.

F is a removable cover for the drain box.

It will thus be seen that any water which may collect in the conduits B will pass through the supplemental duct C (see dotted line Fig. 1) through the inlet orifice C on to the sieve D any solid matter passing through the inlet being caught by the sieve. The water which passes through the sieve passes down the inclined bottom and is drained out through the outlet orifice G into a suitable channel leading to the sewer.

Any water which passes into the casing containing the switch point passes through the openings between the cross bar A. Any chips or other solid foreign matter which passes with the water through the switch point casing is also caught by the sieves "D and D.

H are cross bolts which extend through the switch point casing and through the slots H in the'switch point thereby preventing vehicle wheels passing downwardly between the switch point and the rail and being caught therein, such vehicle wheels riding upon the cross bolts H.

I have made my sieves convex in cross section so as to permitof their free withdrawal from the drain box through the space between the switch point casing and the side of the drain box. It will be readily seen that if the sieves were made flat instead of convex it would be more difficult to accomplish their easy withdrawal.

From this description it will be seen that I have devised a very simple form of switch point casing and drain box which will carry ofi all moisture from the switch point and conduits containing the switch point operating mechanism and which will prevent the clogging of foreign matter between the switch point and rail and which will permit of the easy withdrawal of any solid foreign matter which is retained in the drain box.

WVhat I claim as my invention is.

1. The combination with a Y-shaped rail section having an open bottom and adapted to support a swingable switch point, of a drain box surrounding the switch point casing and extending beneath the same and having an inclined bottom and an outlet orifice extending through the wall of the casing at the lowest point of the incline, and removable screens supported within the drain box beneath the switch point casing, as and for the purposespecified. V

2. The combination with a Y- haped rail section having an open bottom and adapted to support a swingable switch point, of a drain box surrounding the switch point casing and extending beneath the same and having an inclined bottom and an outlet orifice extending through the wall of the casing at the lowest point of the incline, and removable screens removably supported within the drain box casing and formed concave in cross section, as and for the purpose specified.

3. The combination with the switch point casing and conduits containing the switch point operating mechanism, of a drain box having an inlet orifice leading from the aforesaid conduits, an inclined bottom and having an outlet orifice extending through the wall of the casing at the lowest point in such inclined bottom, as and for the pur-" pose specified.
